Code Crusader is a graphical Integrated Development Environment (IDE) designed to smoothly integrate the tasks of working with source files, compiling, and debugging; in short, everything involved in developing code.

EiffelMedia is a multimedia library for Eiffel.
The library allows you to use 2D and 3D graphics,
sound, networking, and input via joystick and
keyboard. It has many smaller frameworks that make
life easier for a multimedia or game programmer.

G2F3 (Generic Game Framework in eiFFel) aims to
simplify the development of two player zero sum
strategy games by separating game specific code
from reusable generic code. So far, abstract board
games are best supported. This software is written
using GNU SmartEiffel. The package comes with six
example games.

EWG (Eiffel Wrapper Generator) is a tool that generates Eiffel wrapper classes for C libraries. It can be used to create libraries that bridge the gap between Eiffel and C. It aims to work for arbitrary ANSI C and with all common Eiffel compilers. It is ideal for creating cross-platform, cross-Eiffel-compiler, and
cross-C-compiler C library wrappers. It can handle pretty much all ANSI C, but understands Visual C and GCC extensions as well.

Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.

Amber for Parrot is an object-oriented scripting
language for the Parrot virtual machine. It
combines the traditional advantages of scripting
languages with support for software correctness
and large-scale software engineering. Amber for
Parrot has syntax and semantics somewhere between
those of Eiffel and Ruby.

eformmail is a stand-alone CGI program that accepts an
HTML form and emails it. The target email
address is not buried in the HTML form,
making it impossible for spammers to take
advantage of this email address. A comprehensive manual is available. eformmail can also validate fields for validity using regular expressions. Since release 2.0 eformmail has a spam tram, so fake form submissions can be dismissed immediately. The proposed email output can be formatted by an XSLT processor.
